Set the flow control feature on each port for a specific mode. The
choices are as follows:
Symmetric – the port operates in Symmetric mode, causing the port to
interpret received PAUSE frames and allow the port to transmit PAUSE
frames when necessary at any speed connection.
Asymmetric Rx – the port operates in Asymmetric Rx mode, causing
the port to interpret received PAUSE frames and prevent the port from
transmitting PAUSE frames. This option is for Gigabit only.
Asymmetric Tx – the port operates in Asymmetric Tx mode, causing
the port to ignore PAUSE frames and allow the port to transmit PAUSE
frames when necessary. This option is for Gigabit only.
Disabled – full duplex flow control is off, causing the port to ignore
received PAUSE frames and prevent the port from transmitting PAUSE
frames at any speed connection.
Auto-Negotiate – when supported, the maximum flow control
capabilities of the port are reflected in the PAUSE bits of the
Auto-Negotiation registers. The ports' flow control operational state is
determined by the results of Auto-Negotiation. This option is not
displayed if Auto-Negotiation is not supported on this port.
To change the settings for full duplex flow control, refer to
Section 5.3.1.
Set the Half Duplex flow control mode. Back pressure half duplex flow
control is enabled when the port is set On, and disabled when the port
is set Off. To change the settings, refer to
Apply the currently displayed settings on the screen to all ports. To
save the settings to all ports, highlight this command and press
ENTER.
